Assembly instruction is available. • √ STURDY & ADJUSTABLE INSERT The sturdy insert keeps the cupcake standing in place and secure from messing up the icing. The insert diameter can be adjusted to fit either a standard or mini cupcake. • √ KEEP CUPCAKES FRESH Made of recyclable food-grade cardboard paper, the individual cupcake containers keep your just baked cupcakes fresh and moist, which is different from the plastic cupcake containers. • √ DIMENSIONS & SPACE SAVING The assembled cupcake box measures 3.5”× 3.5”× 3.5”, and the insert diameter ranges from 1.8” to 2.4”. The window size is 2.1” W × 4” L. Each package includes 60 × brown cupcake boxes and 60 × cupcake inserts, folding flat for easy storage. Cupcake is not included.
